Specification of Letters Patent.

Application filed December 11; 1911. Serial No. 665,146. I

GT all whomit may concern Be it known that I, ALFRED Coron Y, resident of 151 Ash avenue, in the city and dis- I trict'of Montreal, in the Province of Quebec,

in'the Dominion of Canada, a subject of the Emperor of AustriasH'ungary, have invented certain new and usefulfImprovements in Car Construction; and I do hereby declarefthat the following is a full, clear;

and exact-description of the same.

The invention relates to improvements in ear constru'ctiomas' described in the present car, whereby-' the: lates forming the roof are connected by'a ,inel'nber, the latter forming themajorfip'art' in each instance of I the supporting 'trusses.

a. roof absolutely free from leakages, to lighten the construction, and generally to providea cheap and durable structure.v In'the drawings, Figure 11s a cross secj tional perspective View of the car roof. Fig.

2' is an enlarged cross sectional view, partly broken away.- Fig; 3 is an enlargedlongitudinal sectional view; broken away, on the line-AQB in 2.' Fig. 4 is an enlarged perspective detai of the outer end of a car line. Fig. 5 is a perspective detail of a roof plate,*br10ken away'in the center. Fig. 6 is a perspective detail of the end cornerof the I i car, showing the locking flange joint.

Like'numerals of reference indicate corresponding parts n each figure Referring to the-drawings, 1 is a carline in'trough form, having the inwardly turned flanges 2 on top extending from the side walls Band formed at'the bottom in the channel bed 4, said carline extending in an oblique upward direction and downwardly on the other side of the longitudinal center of the carin one length. v

5 are angle brackets, rigidly secured'to the side walls 3 adjacent to the lower ends of the carline 1.

6 is a tie rod, rigidly secured to one of each pair of said brackets 5 and therefore extending across from one end portion of the carline to the other end portion of the carline thereunder and forming with said Patented musin 10- is a super ridge pole covering in the carlines 1 and having corresponding bolt holes therethrough to the bolt holes 9. r

, 11 are bolts extending through the running-board saddles 12 the super ridgev pole 10, beside the carlines 1 and through the ridge pole 7 having their. heads countersunk in the upper sides of said running board saddles 12 and at the lower endthereofthe ridge pole 7 by means of the nuts 11, .said brackets l3'having downwardly extending arms 15 through which the tie rods 6 extend.

16 are the side beams of the frame, re-

cessed at 17 to receive the. trusses formed of,

the carlines 1 and tie rods 6. said trusses being rigidly secured to said side beams 16 by the nuts 18, thus completing the frame of the roof. the walls and under part of the body of the car being constructed in any suitable wav.

19 are the roof plates. formed at the sides thereof with the inwardly curled flanges 20, the upwardly bent flange 21 at the top thereof and at the lower end the downwardly bent flange-22, said flange 21 being again flanged by theinwartland upward curl 23 at h t rne'hd, said plates 19 being of sufficient widithto oceppy the space between the carlineskamfsiightly overlap the side edges of said czn'lines in order that the inwardly curled edges 20 may be run under v I c ofsecruing the brackets 13 to the underside The objects of the invention are to'lessen' the cost of production in steel cars, to devise 25 the inturned flanges 2 and thus make the,

said carlines 1, the joint pieces between the roof plates, the flanges 22 form ng theoverhangs at the edges of the roof, while the upturned flanges 21 rest against the ridge pole sides. I

24 is the crown plate extend ng along the length of the car, over the ridge poles 10 and 7 and under said running board saddles 12, said bolts 11, also extending through said 'crown plate, the latter having the angle 26 are the running boards secured 'nj -t-he or made in sections and having the outwardly and downwardly curled flanged upper edge 2S engaging the curled edges 23' of the roof plates 19, thus relieving the strain on the crown plate 24: without in any Way adding to the rigidity of the construction, that is to say, said locking plate 27 permits the roof the necessary playfor the strains that it is subject to.

In Fig. 6, OIIG'OfIthQ end plates 29 is shown, in which the plate has a side flange 30, extending downwardly and curled at 31 at the under side, said curl being locked by the plate 32 arranged similarly to the locking plate 27 onlyonlthe end walls of the car, said plates 27 and 32 being rigidly secured to the side and end walls of the car.-

It will now be seen that the roof portion of the car is complete and as this application is confined to the construction of the roof, the other parts to the car shall not be set forth. I

The roof plates, as explained, occupy the spaces between the troughed truss members, the carlines of said truss members forming the joint pieces, said joint pieces proving in themselves free runways for the water, and it will be readily seen that it would be quite impossible for the water to back up around the curled edges instead of flowing downwardly and out. of'the troughs. There is only one fastening which in each case penetrates the roof, viz.the bolts 11 'and the heads of these are completely closed in by the center running board, so that it would seem impossible for any water to get into the interior that way, otherwise there is no fastening at all in the way of a break through the metal, and of course, this roof ,IS all 'metal, with the possible exception of the running boards.

The brackets 13 may be held by the single bolts, because the tie rods 6 prevent them from turning, said tie rods can be secured in any suitable way to the brackets 5, either to one of a pair or to two of a pair, as the case may be, for the end of said tie rods plurality of metal plates extending from the ridge pole over the side beams and having inwardly. curled side flanges, a ridge pole, a crown plate engaging the upper ends of said metal plates and arplurality of car lines of truss formation having their tie rods lend ing support to said ridge poles and their rafters centrally supported by said ridge pole, said rafters being a tube like formation and having a longitudinal slot in the upper side from end to end said metal plates loosely hooked on said rafters at the edges ot said slot.
